similar to: Rscript.Rd example (PR#9644)

Hello, I have found what I believe to be a bug in the Linux version of the Rscript binary. Under Windows (official 64-bit 3.5.1 R distribution running on an up-to-date Win10), I can do the following (e.g. under powershell): PS H:\Users\Cesko> Rscript -e 'ls() >> ls()' character(0) character(0) which works as I expect: I am running Rscript with two arguments, namely (1)

I think Rscript has a problem running files that have mac encodings for newline (^M rather than ^J on linux). If I source the file within R, it works okay: > source('j.R') [1] "MEA_data/sernagor_new/CRX_P7_1.txt" But if I run the file using Rscript on a linux box I get a strange error message: $ Rscript --vanilla j.R " Execution halted The example script j.R is at

Hi Dirk, Thanks for the solution. Now I know the work-arounds, but still don't quite get it. Why does R_DEFAULT_PACKAGES has anything to do with library(methods)? If library(h5) works, it should just work, not depend on an environment variable. Rscript is not consistent with R, that's my confusion.

Hi there, I am trying to find an example how to use Rscript Let's suppose I want to pass 3 arguments (I don't want [options] and -e [expressions] as described in help) *on the command line myRscript.R -arg1=value1 -arg2=value2 -arg3=value3 *In the script #! /path/to/Rscript args = commandArgs(TRUE); >From what I see args is just a string, do I do things correctly ? -- View this

Consider this script (with h5 installed): $ cat test.R library(h5) name <- tempfile() f <- h5file(name) file.remove(name) $ Rscript test.R Error in initialize(value, ...) : cannot use object of class "character" in new(): class "H5File" does not extend that class Calls: h5file -> new -> initialize -> initialize Execution halted $ /usr/lib64/R/bin/R --slave

R does a great job with the fine details regarding plots. e.g in the following: library(lattice) y <- -4:4/10 xyplot(y~1, las=1) the y axis is labelled with numbers -0.4, -0.2, 0.0, 0.2, 0.4 with the numbers aligned on the decimal point. How do I get the same behaviour in the colorkey of a levelplot? e.g. levelplot(matrix(y,3,3)) the numbers in the colorkey seem left-aligned, and

Thanks for the details. I?m new to R, and I?m not blaming anything here, just that I?m still not clear what good it makes to keep this inconsistency between R and Rscript. To me (and probably to many others from Perl/Python etc.), this is shockingly weird. I can live with that, and I also want to know why.

A recent paper on visualisation (in Neuron, a leading neuroscience journal) surveyed how well previous articles in this journal labelled their graphs (e.g. axis labelling and describing their error bars). Of particular interest is that (only) 40% of plots labelled what their colorkey was showing (variable and units). The paper is at http://dx.doi.org/10.1016/j.neuron.2012.05.001 R is not yet

Hi, people. I met a little problem for which someone might have a solution. Let's say I have an executable file (named "pp.R") with this contents: #!/usr/bin/Rscript options(echo=TRUE) a <- 1 Sys.sleep(3) a <- 2 If I execute "./pp.R" at the shell prompt, the output shows the timely progress of the script as expected. If I use "./pp.R | tee

Hi, A user of my `optparse` package discovered a bug in Rscript's parsing of [args]. (https://github.com/trevorld/optparse/issues/24) I've reproduced the bug on my machine including compiling and checking the development version of R. I couldn't find a mention of it in the Bug Tracker or New Features. Can be minimally reproduced on the UNIX command line with following commands:

Greetings, I am creating a standalone executable script using Rscript and have run into problems when I define a new S4 class. Here is a small script that demonstrates my problem: #!/usr/bin/env Rscript # # toy.Rscript -- testing S4 class creation in an Rscript setClass("toy", representation(name = "character", price = "numeric"),

Good morning R-help, I have an idiot question: I would like to use getSrcDirectory() and friends to allow me to identify where an R file has been called from when invoked using Rscript. If I understand the documentation correctly, the following example should work: In file test.R: options(keep.source=T) fn<-function(x){x<-x+1} srcDir<-getSrcDirectory(fn) print(srcDir) I

Dear all, finally decided to do an Ubuntu upgrade and a new clean R install from http://cran.r-project.org/bin/linux/ubuntu/. However, while trying to install a package from R-forge I encountered problems, involving error messages saying "Rscript execution error: No such file or directory" (see below). The same procedure works on Ubuntu 11.04 running R 2.12.1-1 from the Ubuntu

Hi all, this is probably some tricky configuration file problem, but I figure someone here might have come across this in the past: In short, I've been using Rscript to run my scripts, usually successfully. But recently I've run into a strange problem, and the only function that causes an error is "print". I can create a file that contains only a print command, and it causes

See the example below (under Ubuntu): $ Rscript -e '1' -e '2' [1] 1 [1] 2 $ Rscript -e '1' -e '' -e '2' ERROR: option '-e' requires an argument $ uname -a Linux xie 3.5.0-25-generic #39-Ubuntu SMP Mon Feb 25 18:26:58 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux Similar problem under Windows: Rscript -e "1" -e "" -e "2" [1]

Dear all, I am trying to use multiple version of R unpacked from CRAN deb files. It does work successfully, except for some packages installation, whether Rscript has been used. I have configured alternatives and switch R environments without any problem and can install most of the packages. '====================================================== $ update-alternatives --display R R - auto

Thanks Tomas. I confirm the quick workaround works for me in the DOS prompt, and when having a shortcut to RScript in SendTo, and when used in the Task Scheduler. I have not tested the R-devel version, due to my unfamiliarity with installing from source code. -----Original Message----- From: Tomas Kalibera [mailto:tomas.kalibera at gmail.com] Sent: Thursday, April 26, 2018 6:34 AM To: Kerry

Hi, I seem to have a problem when passing named parameters to R via Rscript (R2.5.1, bash shell). As soon as I name elements of a list Rscript generates an error. I will appreciate if someone could point to me a correct way of doing this. Thanks, Vadim ## This works bash-3.2$ Rscript.exe -e 'list(1)' [[1]] [1] 1 # and these do not work bash-3.2$ Rscript.exe -e

I figured out how to use quotes and parentheses when using Rscript -e (on a bash shell): Rscript -e write\(1,\"a.txt\"\) --> Question 1: why do the parentheses need to be escaped in the shell? (More a shell than an R question) Then I figured out how to use quotes and parentheses when calling Rscript through system: system('Rscript -e write\\(1,\\\'a.txt\\\'\\)')
